SPECIFICATION forming part of Letters Patent No. 268,663, dated December 5, 1882. Application filed July 31,1882. (No model.) Patented in England November 23. 1881, No. 5,111.

To all whom it may concern:

Be it known that I, JOHN RICHARD HAR- GREAVES, a subject of the Queen of Great Britain, and residing at Haslingden, in the county of Lancaster, England, have invented certain Improvements in Water Fittings and Valves, (for which I have obtained British Letters Patent N 0. 5,111, dated November 23,

i 1881,) of which the following isa specifica- I0 tion.

The object of my invention is to so construct water-littin gs for houses as to facilitate the supply of hot water to elevated situations under the pressure of the cold water from the main; I5 and this objectI attain by combining with the boiler and system of pipinga double .tap or valve, which is connected with the cold-water service, and also with the boiler, so that when the valve is opened cold water passes into the boiler and hot water passes out, to be conveyed through a pipe to the point whereitis needed.

In the accompanying drawings, Figure 1 is a view illustrating my invention as applied to a water-distributing arrangement where water at two places ondifferent levels is to be supplied. Fig. 2 is an enlarged section of a form of valve which may be employed in carrying out my invention, and Fig. 3 a plan view of the valve with the cap removed.

In Fig. 1, a represents a bath, which is shown in section, and 11 represents a sink or washstand, these being two points where water is to be supplied. A fire-place, 0, is provided with a suitable water boiler or heater, d. The pipe e is the cold-water-supply pipe, connected with the service main. This cold-water pipe leads to the bath a, andis there provided with an ordinary tap or valve, f, and a branch, 0, supplies a tap, g, over the sink with cold water. An extension, 0 of the said branch is connected with a double valve, h, which I have devised for the purposeof'myinvention. Such a valve is represented drawn to a larger scale in Figs. 2 and 3, and is formed withthree branches, 6, 7c, and l. The branch la is for the cold-water supply to the tap, and in the example would be coupled up with the pipe 6 which brings cold water fl'OLllhllG main. The branch i conveys cold water to the boiler, and would be coupled with the pipe m, which is connected 0 with the lower part of the boiler, as seen in Fig. 1. The branch lie for the supply of hot water to the tap, and would be coupled with the pipe 11, which is connected with the upper part of the boiler. The branches are arranged 5 5 to suit the requirements of the varying dispositions of the pipes. The bath is provided with a similar tap, h, which is the tap selected for illustration in Fig. 2, the two taps differing only in the directions in which the cold-water service branches lo leave the bodies of the taps. The tap his supplied with cold water from the pipee by means of a branch, 0 and the branches iandlof the tap are connected with the pipes m and n by means of the pipes m and a. Each 6 of the taps h and h is provided with two valves, 0 and 1), Fig. 2, the valve 0 closing'the outletpassage for hot water and the valve 19 closing the outlet-passage for the cold-water service. The two valves are simultaneously pressed 7o downward onto their seats by means of a screw-spindle,r, which is provided atits lower end with a disk which presses upon the spindles of the valves when the screw-spindle is turned in the ordinary way to close the valves.

The action of the tap is as follows When the spindle r is turned to open the tap the cold water flows through the "alve-seat into the passage 6 and passes into the boiler, thereby displacing hot Water, which flows through the pipen and the seat of the valve 0, and is discharged through the bib into the bath or other receptacle, as the case may be. To prevent the cold water from the valve 1) from flow-i ing toward the bib the said valve is covered 8 by means of a removable ring, 3, against which a washer upon the valve is pressed when the valve opens.

In order to allow for the expansion and contraction of the water in the boiler, and in the pipes which are connected therewith, a pipe which is open to the atmosphere at its upper end extends to a higher level than the highest point at which but water is supplied-that is to say, in the example, to a higher point than 5 the tap h. In the example the pipe at is con 2 4 assess ti nued upward but, if preferred, a separate pipe a water-boiler with a cold-water-supply pipe may extend upward from the pipe at, or directly leading to the boiler through passages in said from the boiler, and in some cases may be situated within the chimney or flue.

I do not confine myself to the precise arrangement of the pipes as represented in the drawings, the said pipes having been partly arranged to suit the convenience ofillustration, and I do not confine myself to the particular form of tap illustrated by Figs. 2 and 3, but may use any other suitable form of two or three way tap; nor do I confine myself to the precise application to the bath and sink, as hot water may be supplied to one, two, or more places for any purpose, as required.

I claim as my invention- The combination of a compound valve and valve, and a hot-water-distributing pipe leading from said boiler, and having an outlet through said valve, all substantially as described, whereby on the opening of the valve cold water will be admitted to the boiler as the hot water is withdrawn.

In testimony whereof Ihavesigned my name to this specification in the presence of two subscribing witnesses.
